Solid aluminium pulley for reliable power transfer

The 3Racing Aluminum Differential Pulley Gear T39, model 3RAC-3PY/39, provides a sturdy replacement option for RC drivetrains. Machined from aluminium, it aims to give hobbyists a balance of strength and minimal added weight during upgrades.

Main benefits of the 3Racing T39 pulley

Material: Aluminium construction for improved wear resistance and stable performance.
Tooth Count: T39 teeth for consistent meshing and efficient torque delivery.
Compatibility: Fits many RC models that use a T39 pulley specification.
Function: Helps tighten up drivetrain response and keeps power transfer smooth under load.

Do I need to change bearings when fitting this pulley?

Not always, but inspect existing bearings for wear. Fresh bearings can help the aluminium pulley run quietly and reduce vibration in the drivetrain.

Is the 3RAC-3PY/39 suitable for competitive use?

Yes, its metal construction makes it more robust than stock plastic parts, offering consistency over repeated runs which is useful in competitive settings.

Should I lubricate the pulley teeth?

Keep the teeth free of grime; general drivetrain grease is not usually applied to pulley teeth. Clean periodically to maintain smooth operation of the 3Racing pulley.
